Product Highlights

Sunlight readable 3500 nits brightness, fanless thermal management, Intel® Smart Display Module ready (option), blackening defect-free in direct sunlight, narrow 8.5 mm bezel for video wall applications, 1080p Full HD resolution.

TrueColor™ Calibrated

Each screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, but also accurately reproduces brand colors, skin tones, and colorways.

Blackening Defect Free

Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS491LT4-M is equipped with a high temperature LCD panel capable of withstanding temperatures up to 110˚C (230°F) without blackening – crucial for direct sunlight applications.

Auto Brightness Control

Different external lighting conditions require different brightness levels. An onboard light sensor measures the ambient light in the area and automatically adjusts the image accordingly.

Intel® SDM Ready

An Intel® SDM slot to accept an Intel® Smart Display Module (sold separately). Supporting a variety of modern x64 operating systems, Intel® SDM delivers the same level of intelligence and interoperability as the Open Pluggable Specification, but in a smaller form factor. Compatible with both the Intel® Small (Intel® SDM–S) and Intel® SDM Large (Intel® SDM–L) form factors.

Narrow Bezel for Video Walls

The DS491LT4-M features an 8.5 mm narrow bezel display – perfect for video wall applications. With built-in video daisy chaining, a single 1080p source can be used on video walls up to 15×15 in size without the need for any additional external video wall controller.
